Bar code types
During installation, the type of bar code used is defined for each mode.
The Bar Code Reader is capable of reading and decoding three
different types of bar codes.
• Code 3 of 9 — also known as Code 39, is a widely used code in
which 9 bars or spaces comprise the characters, 3 of which are
wide.
• Interleaved 2 of 5 — or I 2 of 5, is a compact, interleaved code for
numeric characters only. Each digit is represented by 5 bars or
spaces, 2 of which are wide.
• Codabar — similar to Code 3 of 9, but not as widely used. Codabar
includes only numeric and special characters.
The following table shows a comparison of bar code types:
